CARPET-STRETCH ER.

SPECIFICATION forming part Of Letters Patent N0. 439,327, dated October 28, 1890.

Application filed May 14, 1889. Serial No. 310,783. (No model.)

To all whom it may concern,.-

Be it known that I, FRED l-I. RUNDELL, a citizen of the United States, residing at Moravia, in the county of Cayuga and State of New York, have invented a new and useful Carpet-Stretcher, of which the following is a specification.

My invention relates to that class of carpetstretch ers in which a sliding cross-bar engages with the carpet and is operated by a rope connected to it, then passing forward-over a pulley, and thence back to a windlass.

The object of my invention is to improve this implement in its detail construction, viz: in slotting the holding-bar substantially its whole length, in connecting the Windiass with the cross-arm through this slotway so that when the rope is wrapped around the Windlass the cross-bar and windlass move together toward the wall, and in locking the rope upon the pulley by a pivotal cam having a serrated face.

My invention consists in a carpet-stretcher embodying the above-setforth special points of novelty in its construction and operation.

It is constructed as follows, reference being had to the accompanyingdrawings, in which- Figure lis an isomctrical elevation. Fig. 2 is a vertical longitudinal section through the slot and the end bar of the frame.

A is the holding-bar, provided with alongitudinal slot l extending substantially the whole length, and in its front end in the slot I secure the holding-spike 2. This consists of a head, ears 3, lying on top of the holding bar, a body fitting through the slot l, a sharpened point projecting below the bar, and a bolt-hole receiving a bolt which holds the spike in place. The point is forced into the floor by the blows of a hammer upon the head. In the slot l and behind the spikel pivotally mount the locking-cam 4, having its face transversely serrated and provided with the side ears 5, which prevent the upper end from dropping down into the slot when loose. Contiguous to this cam I journal a grooved pulley in the slotway, as shown by dotted lines, over which the rope 6 passes.

B is the cross-bar, having teeth projecting below its lower face, mounted beneath the bar A and transverse thereto upon a bolt or pin 7, which bolt passes up through the slotwayl through the plate 8 and through the windlass 9, thus directly connecting the windlass and cross-bar vertically. The plate 8 lies upon the top of the bar A and between it and the windlass, and is provided with a fin l0,which lits loosely in the slotway and guides the windlass in line with the slotway and in the true line of draft.

The rope 6 has one end secured to the windlass and the other to the cross-bar extending forward around the pulley. When the windlass is rotated, the rope winds up thereon, and this draws the cross-bar toward the front end of the holding-bar A, and the windlass also travels simultaneously and coincidently with the cross-bar in the same direction. Then when the carpet is sufficiently stretched I throw the cam over against the rope, and with a blow from a hammer grip the rope against the pulley and hol'd the cross-bar from being drawn backward by the strain of the carpet. It will be observed that by this vertical connection between the windlass and cross-bar and the interposition of the plate between the windlass and bar A the cross-bar cannot tilt or twist, neither can the Windlass be inclined out of avertical lin e, and consequently the best results are obtained with a minimum of power.

l. A carpet-stretcherV consisting of a vertically and longitudinally slotted bar, a holdingspike secured in its front end, a cam mounted in the slot near the front end, a pulley mounted in said slot contiguous to the cam, a cross-bar provided with teeth and mounted beneath the bar and vertically connected to the Windlass through said slot, and the sliding plate S, which has a downwardly-projecting lug 10, the lower face of which rests upon the upper face of the cross-bar for the purpose of keeping the said cross-bar from turning over, a Windlass on top of the bar and plate, and a rope secured at one end to the windlass and passing over the pulley and connected at its other end to the cross-hangin combination, as set forth.

2. A carpet-stretcher consisting of a main bar slotted vertically and longitudinally, a holding-spike secured in the slot, having a head standing above the bar, side ears resting upon the bar, and a pointprojecting below it,

ICO

a cam mounted in the slot adjacent to the spike, a pulley mounted in the slot contiguous to the cam,a cross-bar having teeth mounted beneath the bar and vertically and rigidly secured to the Windlass, a plate having a' iin iitting in said slot, a Windlass. resting upon said plate, and a rope secured to the windlass and the cross-bar and extending over th'e pulley, in combination, as set forth.

3. The combination, With the main bar slotted vertically and longitudinally, of a spike secured in the slotand provided with a head standing above the bar, side flanges resting upon it and a point extending below it.

4. The combination, with the slotted bar A, of a pulley mounted in the slot, a drawrope tting over the pulley, and a cam mounted in the slot contiguous to the front of the pulley and arranged to grip the rope upon the pulley, as set forth.

5. The combination, with the slotted barA and a pulley mounted in the slot and a windlass mounted above the bar, a cross-bar below the bar, connected vertically by a bolt passing vertically through the slot, and a rope conneeted to the Windlass and cross-bar and passlng over the pulley, as set forth.
